powerpc/via-pmu-led.c: Add of_node_put to avoid memory leak

2010-09-02T04:07:33+00:00

Add a call to of_node_put in the error handling code following a call to
of_find_node_by_path.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@r exists@
local idexpression x;
expression E,E1;
statement S;
@@

*x =
(of_find_node_by_path
|of_find_node_by_name
|of_find_node_by_phandle
|of_get_parent
|of_get_next_parent
|of_get_next_child
|of_find_compatible_node
|of_match_node
)(...);
...
if (x == NULL) S
<... when != x = E
*if (...) {
  ... when != of_node_put(x)
      when != if (...) { ... of_node_put(x); ... }
(
  return <+...x...+>;
|
*  return ...;
)
}
...>
of_node_put(x);

[POWERPC] via-pmu: remove LED sleep notifier

2007-05-08T01:54:19+00:00

The generic LED code now makes sure that suspended devices don't blink,
so we no longer need to do it ourselves. For the suspend to disk case,
however, we need to make sure that we don't blink if the PMU sysdev
was suspended before the LED device.

[POWERPC] PMU LED whitelisting of PowerMac 7,2 and 7,3

2007-04-12T17:55:14+00:00

This allows the PMU LED on both a PowerMac 7,2 (Dual G5 2.0GHz, June 2003)
and a PowerMac 7,3 (Dual G5 2.0GHz, June 2004) to be controlled.
The physical LED is never off, unlike an iBook/PowerBook LED.
It is rather dim ("off") or very bright ("on").

[POWERPC] powermac: disallow pmu sleep notifiers from aborting sleep

2007-03-26T02:35:17+00:00

Tracing through the code, no current PMU sleep notifier can abort sleep.
Since no new PMU sleep notifiers should be added, this patch simplifies the
code and removes the ability to abort sleep.

[POWERPC] powermac: Constify & voidify get_property()

2006-07-31T05:55:05+00:00

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

powermac platform & macintosh driver changes.
